As another possibility,  I can give you some experimental
kernel code that basically is integrated with the multicast
tunnel code in the kernel and gives you a device called
"mvif0" that allows you to put a route between two boxes
and route all packets to a destination X between a tunnel system Y.
Logically:
	send all unicast packets to X via ip dst Y (ip dst in outer
	ipip protocol packet)

This is for support of mobile ip, what at this point I can
at least do by statically inserting routes in the kernel. 
I sent about 20000 packets through it yesterday so it isn't
that bad, but it's still experimental.

Depends on what you want to do.
